It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

Now if I were to solve these two corners then the red-yellow part would be on the same edge of the cube.

现在如果我要解决这两个角落的话，红黄壤的一部分，将在同一边缘的立方体。

After phosphogypsum application, phosphorus content in broomcorn seedling is 1.17~2.43 times that in lime treatment.

While it is contrary that the more contents of Fe,Ca and P are in yellow soil at higher altitude than those in lateritic red soil;(4) The pine forest has the highest content of Pb,and the Pb content is higher in soil at low altitude than that in high altitude.

鼎湖山土壤二氧化硅，锰含量随着海拔梯度的上升而下降，赤红壤含量高于黄壤；然而铁含量则随着海拔梯度的上升呈上升趋势，赤红壤含量低于黄壤，钙全量含量和磷含量也是赤红壤低于黄壤。（4）土壤Pb马尾松林含量最高，随着海拔梯度上升含量有下降趋势。

The gray brown podzolic soil is distributed in areas ranging from 7,000 to 8,500 feet in elevation.

灰棕壤——灰化黄壤组合：在拔海7000—8000尺地带，森林下仍是灰棕壤，而草地上则为灰化黄壤。

Author was menstruated content of boron and researched the status of lack of Boron and researched relativity of its Influencing facto, the results showed that the average content of available boron in the yellow soil was 0.39±0.27 mg/kg, 80 percent of its was under 0.5mg/kg which was lack for boron and 17.44 percent of its was under 0.2mg/kg which was especially lack for boron; The distribute frequencies of available boron contents of yellow soils in Chongqing was dispersedly, its range of 0.07mg/kg to 1.99mg/kg. The diversity of different zoology area was distinct. The result of pertinence analyses showed that available boron contents had correlativity with the pH(r=0.181** n=281) and CEC（r=0.124** n=281 and It had correlativity with Organic matte When the content of organic matte is high; in addition, soil granule、clime was the Influencing factor of availability of boron in Yellow Soils in Chongqing.

笔者通过调查取样对重庆市黄壤硼的含量进行测定并分析了缺硼的程度，对其影响因素进行了相关性分析，研究结果表明：重庆市黄壤有效硼的平均含量为0.39±0.27mg/kg，其中近80%的土壤样品有效硼含量低于0.5mg/kg，属于低硼或缺硼土壤，还有17.44%的土壤样品有效硼含量低于0.2mg/kg，属于极度缺硼的土壤；而有效硼含量的分布频率比较分散，变幅较大，从0.07mg/kg~1.99mg/kg，变异系数达到69.41%，不同生态类型区土壤有效硼含量的差异十分明显；而相关性分析结果表明：土壤有效硼与土壤pH值(r=0.181** n=281)和CEC（r=0.124** n=281呈正相关，在有机质含量较高的条件下与其相关性也较为显著（r=0.347** n=90，而土壤质地以及气候也对重庆市黄壤硼的有效性有很大的影响

The maximum rate of decomposition of soil organic carbon insubtropical wetness area is red soil under coniferous and broad-leaved mixed forest＞yellowsoil under grass＞yellow soil under shrub＞yellow soil under broad-leaved forest＞red soilunder camellia oleifera; decomposition rate of yellow soil is faster than red soil. Themaximum rate of decomposition of soil organic carbon in subtropical wetness zone isyellow-brown soil under mixed forest in Nanjing＞red soil under adult fir in Yujiang＞redsoil under broad-leaved forest in Yujiang.

湿润亚热带地区森林土壤有机碳分解速率最大值出现在培养初期的一周内，其顺序：针阔混交林红壤＞茅草黄壤＞灌木林黄壤＞常绿阔叶林黄壤＞油茶红壤，同一植被下黄壤有机碳分解速率大于红壤，南京混交林黄棕壤＞余江杉木(32年)红壤＞余江常绿阔叶林红壤。

Plunder melds and run with this jewel!
